Abstract [en]
Crushed rocks are in general more flaky and irregular in shape than natural aggregates. Moreover the crushed rocks give more fine material. Fillers can in combination with superplasticizers be used to expand the paste phase of the concrete and thus be used to lower the cement consumption. To utilize the filler optimally you need to evaluate the filler quality. There are several methods to evaluate the filler. In this article different methods both as regard the material properties and the behavior in mortar and paste tests are compared and evaluated. The analysis shows the importance of understanding the effect of flakiness and the properties of the finest fraction < 10 µm.
